Question

我想使用独立的石英调度程序为状态机传奇重新设置消息调度。现在它适用于普通消费者，但是我无法正确设置重新传播。我的传奇配置如下所示：

MassTransit.Bus.Factory.CreateUsingRabbitMq(cfg =>
        {
            var retryPolicy = Retry.Incremental(5, TimeSpan.FromSeconds(5), TimeSpan.FromSeconds(2));

            cfg.UseMessageScheduler(new Uri($"rabbitmq://localhost/SchedulerQueue"));

            var host = cfg.Host(new Uri(uri), h =>
            {
                h.Username(config.RabbitMqUser);
                h.Password(config.RabbitMqPassword);
            });

            cfg.ReceiveEndpoint(host, "SagaQueue", e =>
            {
                e.Durable = true;

                e.StateMachineSaga(new MySaga(),
                    repository, c =>
                    {
                        c.UseTransaction();
                        c.Message<ISagaEvent>(y => y.UseScheduledRedelivery(retryPolicy));
                    });
            });
        });

其中ISagaEvent是由saga处理的消息。我做错了什么，有没有办法为传奇配置预定的重新传递？

要在传奇中进行计划，通常最好使用实际的状态机计划功能，因此更新传奇的状态以指示重新传递。

基本上，如果您收到一个尚未准备好的状态的事件，请使用int main() { srand(static_cast<unsigned int>(time(0))); int secretNumber = rand() % 64 + 1; int tries = 0; int High = 64; int Low = 1; int guess = rand() % High + Low; cout << "\tWelcome to Guess My Number\n\n"; do { int guess = rand() % High + Low; ++tries; if (guess > secretNumber) { cout << "Too high!\n\n"; cout << "\n"<<guess; int High = guess - 1; } else if (guess < secretNumber) { cout << "Too low!\n\n"; cout <<"\n"<< guess; int Low = guess + 1; } else { cout << "\nThat's it!You got it in" << tries << "guesses!\n"; system("pause"); return 0; } } while (guess != secretNumber); system("pause"); return 0; }在将来的某个时间安排该消息，此时该事件可能处于可能的状态处理。
